The ALA “State of America’s Libraries Report 2018” had an interesting summary of current trends in services that academic libraries are providing. The 2019 report states that instructional services provided by library staff have risen to over 7 million.

Services

Although almost two-thirds of libraries reported flat budgets, new services continue to grow. The top five new services currently supported by academic libraries are web development, open access institutional repositories, learning systems, digital humanities, and digital media production. Other services supported by library staff include massive open online course (MOOC) development, e-portfolio development, makerspaces, and Geographic Information Systems (GIS). Most academic libraries employ staff to provide specialized assistance with copyright, metadata, data management, research impact, instructional design, and data visualization.

In the past five years, more than 58% of all academic libraries have changed their reference staffing models, with the most popular change being a switch to on-call staffing. Academic libraries also provide staff and other support to such campus services as writing centers (42%), tutoring (39%), testing (25%), diversity and equity (12%), and digital scholarship labs (11%).

Academic library staff provided instructional sessions (face-to-face as well as electronic) for more than 6.2 million students. Almost 43% of these sessions were digital.
